.SH "BESCHREIBUNG"
.PP
When invoked without the
\fB\-D\fR
option, the
\fBuseradd\fR
command creates a new user account using the values specified on the command line plus the default values from the system\&. Depending on command line options, the
\fBuseradd\fR
command will update system files and may also create the new user\*(Aqs home directory and copy initial files\&.
.PP
By default, a group will also be created for the new user (see
\fB\-g\fR,
\fB\-N\fR,
\fB\-U\fR, and
\fBUSERGROUPS_ENAB\fR)\&.
.SH "OPTIONEN"
.PP
The options which apply to the
\fBuseradd\fR
command are:
.PP
\fB\-\-badname\fR\ \&
.RS 4
Allow names that do not conform to standards\&.
.RE
.PP
\fB\-b\fR, \fB\-\-base\-dir\fR\ \&\fIBASE_DIR\fR
.RS 4
The default base directory for the system if
\fB\-d\fR\ \&\fIHOME_DIR\fR
is not specified\&.
\fIBASE_DIR\fR
is concatenated with the account name to define the home directory\&. If the
\fB\-m\fR
option is not used,
\fIBASE_DIR\fR
must exist\&.
.sp
If this option is not specified,
\fBuseradd\fR
will use the base directory specified by the
\fBHOME\fR
variable in
/etc/default/useradd, or
/home
by default\&.
.RE
.PP
\fB\-c\fR, \fB\-\-comment\fR\ \&\fICOMMENT\fR
.RS 4
Eine beliebige Zeichenkette\&. Dies ist f\(:ur gew\(:ohnlich eine kurze Beschreibung des Logins und wird im Moment im Feld f\(:ur den vollst\(:andigen Namen des Benutzers gespeichert\&.
.RE
.PP
\fB\-d\fR, \fB\-\-home\-dir\fR\ \&\fIHOME_DIR\fR
.RS 4
The new user will be created using
\fIHOME_DIR\fR
as the value for the user\*(Aqs login directory\&. The default is to append the
\fILOGIN\fR
name to
\fIBASE_DIR\fR
and use that as the login directory name\&. If the directory
\fIHOME_DIR\fR
does not exist, then it will be created unless the
\fB\-M\fR
option is specified\&.
.RE

Lesen Sie dazu unten den Abschnitt \(FcDie Standardwerte ver\(:andern\(Fo\&.
.RE
.PP
\fB\-e\fR, \fB\-\-expiredate\fR\ \&\fIEXPIRE_DATE\fR
.RS 4
The date on which the user account will be disabled\&. The date is specified in the format
\fIYYYY\-MM\-DD\fR\&.
.sp
If not specified,
\fBuseradd\fR
will use the default expiry date specified by the
\fBEXPIRE\fR
variable in
/etc/default/useradd, or an empty string (no expiry) by default\&.
.RE
.PP
\fB\-f\fR, \fB\-\-inactive\fR\ \&\fIINACTIVE\fR
.RS 4
Die Anzahl von Tagen nach Ablaufen des Passworts bis das Konto dauerhaft deaktiviert wird\&. Ein Wert von 0 deaktiviert das Konto, sobald das Passwort abl\(:auft\&. Ein Wert von \-1 schaltet diese Funktion ab\&.
.sp
If not specified,
\fBuseradd\fR
will use the default inactivity period specified by the
\fBINACTIVE\fR
variable in
/etc/default/useradd, or \-1 by default\&.
.RE
.PP
\fB\-g\fR, \fB\-\-gid\fR\ \&\fIGROUP\fR
.RS 4
Der Name oder die Nummer der anf\(:anglichen Anmeldegruppe des Benutzers\&. Der Gruppenname muss existieren\&. Die Gruppenzahl muss auf eine bereits vorhandene Gruppe verweisen\&.
.sp
If not specified, the behavior of
\fBuseradd\fR
will depend on the
\fBUSERGROUPS_ENAB\fR
variable in
/etc/login\&.defs\&. If this variable is set to
\fIyes\fR
(or
\fB\-U/\-\-user\-group\fR
is specified on the command line), a group will be created for the user, with the same name as her loginname\&. If the variable is set to
\fIno\fR
(or
\fB\-N/\-\-no\-user\-group\fR
is specified on the command line), useradd will set the primary group of the new user to the value specified by the
\fBGROUP\fR

The skeleton directory, which contains files and directories to be copied in the user\*(Aqs home directory, when the home directory is created by
\fBuseradd\fR\&.
.sp
This option is only valid if the
\fB\-m\fR

\fB\-\-create\-home\fR) option is specified\&.
.sp
If this option is not set, the skeleton directory is defined by the

Example:
\fB\-K\fR\ \&\fIPASS_MAX_DAYS\fR=\fI\-1\fR
can be used when creating system account to turn off password aging, even though system account has no password at all\&. Multiple

.RE

By default, the user\*(Aqs entries in the lastlog and faillog databases are reset to avoid reusing the entry from a previously deleted user\&.
.RE
.PP
\fB\-m\fR, \fB\-\-create\-home\fR
.RS 4
Create the user\*(Aqs home directory if it does not exist\&. The files and directories contained in the skeleton directory (which can be defined with the
\fB\-k\fR
option) will be copied to the home directory\&.
.sp
By default, if this option is not specified and
\fBCREATE_HOME\fR
is not enabled, no home directories are created\&.
.sp
The directory where the user\*(Aqs home directory is created must exist and have proper SELinux context and permissions\&. Otherwise the user\*(Aqs home directory cannot be created or accessed\&.
.RE
.PP
\fB\-M\fR, \fB\-\-no\-create\-home\fR

variable in
/etc/default/useradd\&.
.sp
The default behavior (if the
\fB\-g\fR,

options are not specified) is defined by the
\fBUSERGROUPS_ENAB\fR
variable in
/etc/login\&.defs\&.
